The education (particularly graduate education) of Americans
who were active in astronomical research between 1876 and 1941
is assessed for its effectiveness in preparing the astronomers for
careers in research. This period contains three dynamic changes:
the growth of American astronomy in becoming the world's leading
community of astronomers, the...
Fish diseases and various parameters associated with disease
caused mortality of fish were monitored at the Oregon State University
Marine Science Center and at a private mariculture facility on
Yaquina Bay during a period of five years. Nearly all disease problems
observed were caused by Vibrio anguillarum and Vibrio spp....
There is renewed interest in North America for the use of calcium aluminate cement (CAC) in infrastructure repair. The interest is driven by the specialty properties that make CAC the ideal candidate for particular applications. These include rapid strength gain, even at temperatures approaching 0°C, the ability to customize fresh...
To examine the macrophage response to M. avium, I compared inflammasome and cytosolic sensor expression and activation. My result demonstrated that virulent strains of M. avium (A5 and 104) suppress IL-1β production and induce IFN-β production in macrophages. M. avium mutants deficient at DNA export in the biofilm exhibited reduced...
Thermoelectric materials are playing a larger role in the global effort to
develop diverse, efficient, and sustainable energy technologies: primarily through
power-generating thermoelectric modules. The principal components of
thermoelectric modules are solid-state thermoelectric materials – typically heavily
doped semiconductors – that convert heat directly into electricity. However, this
conversion efficiency...
The central purposes of this study were to review the
historical sources of David Kolb's formulation of experiential
learning theory, and to determine the effect and
application of Kolb's theory and Learning Style Inventory
as reflected in the literature between 1971 and 1990.
It was found that Kolb based his...
To determine whether membrane-related events may be involved in
attenuated luteal function after gonadotropin-releasing hormone (GnRH)
administration, corpora lutea (CL) were removed from 10 beef heifers on day 7
of the estrous cycle after i.v. injection of GnRH or saline on day 2 of the cycle.
Luteal slices were incubated...
The taste qualities of acidulants have not been studied in detail despite
the fact that they are widely used by the food industry. Studies on
characterizing the sensory properties of organic and inorganic acids are very
limited. Reported studies are commonly on threshold, equi-sour and the time
intensity values of...
Reintroduction programs are increasingly being used to save animals from extinction and aid in their recovery. The California Condor (Gymnogyps californianus), one of the most endangered birds in the world, is a remarkable example of how reintroduction programs can help rapidly increase a species' population numbers and range following a...
Microstructure changes in uranium and uranium/metal alloys due to radiation damage are of great interest in nuclear science and engineering. Titanium has attracted attention because of its similarity to Zr. It has been proposed for use in the second generation of fusion reactors due to its resistance to radiation-induced swelling....
